This Code of Ethics represents a significant milestone as the first in the Republic of Tanzania, providing essential guidance for psychologists and mental health practitioners nationwide. As the first Code of Ethics for Psychology to be implemented in The Republic of Tanzania, its primary purpose is to provide psychologists and mental health workers with a guide for navigating ethical decisions in the practice of psychology. This document is not all-encompassing, nor is it a legal document. Moreover, it is not intended to be a strict set of rules but rather a framework for fostering an ethical culture within the field of psychology.
